Donor (outdoor) antenna
Captures weak outdoor cell signal. Placement and aim matter more than amp model. Keep it clear of other roof RF when possible.

weBoost install — Authorized Installer, AGC honesty
A cell booster does not create signal out of nothing — it amplifies whatever weak signal already reaches your roof antenna. Install it wrong and you can end up with worse performance than no booster at all. United Mobile RV is a weBoost Authorized Installer.

Field notes
We place donor and indoor antennas to reduce oscillation and let automatic gain control (AGC) do its job. We do not promise magic bars where outdoor RF is not there. Measure outside first — dead outdoor cell is a coverage problem, not a missing amp.
Three parts, one system
Amplifier
Boosts what the donor hears. Cable quality and ground-plane choices matter. weBoost uses AGC — we do not “tune gain” like a stereo.
Indoor antenna
Rebroadcasts inside the coach. Must be isolated from the donor. Too close and you get oscillation feedback.
Power
Fused DC into the coach electrical system. No dangling cigarette-lighter specials for a travel install.
AGC & oscillation
What AGC does
Automatic gain control reduces boost when the amp hears its own output or when outdoor signal is already strong. Separation and isolation keep AGC from slamming gain to the floor.
Oscillation feedback
If outdoor and indoor antennas are too close, the amplifier picks up its own output and re-amplifies it. The system detects that and cuts gain — performance collapses.
Authorized Installer honesty
Placement and signal optimization — not “guaranteed bars” in a dead canyon. Outdoor RF and clear sightlines still win.
With Starlink / Peplink
Roof real estate is finite. Separate weBoost donor antennas from Starlink and Peplink cellular antennas. Crowding one corner creates interference that looks like bad firmware.
Owner checklist
- Measure outdoor signal before buying — weak-but-present, not dead
- Maximize separation between donor and indoor antennas
- Use quality coax; avoid sharp bends and crushed runs
- Fuse DC power; label the circuit
- If bars look worse after install, assume oscillation until proven otherwise — see weBoost no-boost troubleshoot
DIY vs book UMRT
Reasonable DIY
Kit unpack, app setup, temporary placement tests on a site with known weak signal — if you already have a fused power path and will not drill new penetrations.
Book us when
Permanent roof donor mount, sealed penetrations, clean coax routes, oscillation that will not clear, or you want the booster designed alongside Starlink/Peplink on the same roof.
Site survey in five minutes
Outside first
Stand outside the coach with the phone on the carrier you care about. If there is nothing usable outdoors, a booster will not invent it.
Inside vs outside delta
If outside is usable and inside is dead, the shell is shielding you — that is the booster use case. If outside is already dead, fix coverage path (different carrier, Starlink, or relocate) first.
Donor aim
Point toward the usable sector when the kit supports directional donors. Omnidirectional kits still need height and clear metal clutter.
After install test
Compare before/after speed and call quality at the same outdoor site. If performance got worse, assume oscillation or donor/indoor coupling until proven otherwise.
FAQ
Will weBoost work with no bars outside?
No. It amplifies existing outdoor signal. Dead outside stays dead.
Can you tune the gain?
weBoost uses AGC. We optimize placement and isolation so AGC does not throttle itself into the floor.
Does it replace Starlink?
No. Cell for low latency near towers; Starlink where towers disappear. Many travelers run both — Peplink coordinates them.
Why did bars get worse after install?
Classic oscillation or antennas too close. Separate donor and indoor, check coax damage, then retest. See the no-boost troubleshoot page.
